its likelly not hostapd. i do use wds sta and wds ap modes with latest 
hostapd.
i have a different idea. hostapd is creating a ap vlan type interface 
for each wds station associating and there was a issue i had with a 
patch in mac80211 a while ago
since something was changed regarding vlan ap handling in mac80211

take a look on the following patches

the second one broke wds sta operation for me completelly. i never 
checked the second one. my advise. revert them both and try it again and 
report if its working then. i was originally complaining already on this 
mailinglist about the breakage, but it seems that my comment was ignored 
at the end

The hostapd (in AP side) didn't include the sta in the bridge when the security policy is WPA-PSK or WPA-EAP. With none policy the sta is correctly included.
